How to twist an object with Sverchok?
This is one way to do it. currently:




first split the verts of the object
then multiply each vert's vector by a unique matrix (which is some function of z-height here i'm multiplying the vertex's Z component by 51.94) 
then recombine using mesh_join.


We don't have a proportional editing method inside sverchok, you'd need to combine math nodes to emulate that feature. Not impossible, this layout should suggest further development.
